# Claude Code Usage
Check your Claude Code OAuth API usage limits for both session (5-hour) and weekly (7-day) windows.
## Quick Start
```bash
cd {baseDir}
./scripts/claude-usage.sh
```
## Usage
```bash
# Default: show cached usage (if fresh)
./scripts/claude-usage.sh
# Force refresh from API
./scripts/claude-usage.sh --fresh
# JSON output
./scripts/claude-usage.sh --json
# Custom cache TTL
./scripts/claude-usage.sh --cache-ttl 300
```
## Output
**Text format** (default):
```
🦞 Claude Code Usage
⏱️ Session (5h): 🟢 ████░░░░░░ 40%
Resets in: 2h 15m
📅 Weekly (7d): 🟡 ██████░░░░ 60%
Resets in: 3d 8h
```
**JSON format** (`--json`):
```json
{
"session": {
"utilization": 40,
"resets_in": "2h 15m",
"resets_at": "2026-01-19T22:15:00Z"
},
"weekly": {
"utilization": 60,
"resets_in": "3d 8h",
"resets_at": "2026-01-22T04:00:00Z"
},
"cached_at": "2026-01-19T20:00:00Z"
}
```
## Features
- 📊 **Session limit** (5-hour window) - Short-term rate limit
- 📅 **Weekly limit** (7-day window) - Long-term rate limit
- ⚡ **Smart caching** - 60-second cache to avoid API spam
- 🎨 **Beautiful output** - Progress bars, emojis, color-coded status
- 🔄 **Force refresh** - `--fresh` flag to bypass cache
- 📤 **JSON output** - Machine-readable format
- 🔔 **Automated monitoring** - Get notified when quotas reset
## Status Indicators
- 🟢 **Green** - 0-50% usage (healthy)
- 🟡 **Yellow** - 51-80% usage (moderate)
- 🔴 **Red** - 81-100% usage (high/critical)
## Requirements
- **macOS**: Uses Keychain to access Claude Code credentials
- **Linux**: Uses `secret-tool` for credential storage
- **Credentials**: Must have Claude Code CLI authenticated
## How It Works
1. Retrieves OAuth token from system keychain
2. Queries `api.anthropic.com/api/oauth/usage` with OAuth bearer token
3. Parses `five_hour` and `seven_day` utilization metrics
4. Calculates time remaining until reset
5. Formats output with progress bars and status indicators
6. Caches result for 60 seconds (configurable)
## Cache
Default cache: `/tmp/claude-usage-cache` (60s TTL)
Override:
```bash
CACHE_FILE=/tmp/my-cache CACHE_TTL=300 ./scripts/claude-usage.sh
```
## Examples
**Check usage before starting work:**
```bash
./scripts/claude-usage.sh --fresh
```
**Integrate with statusline:**
```bash
usage=$(./scripts/claude-usage.sh | grep "Session" | awk '{print $NF}')
echo "Session: $usage"
```
**Get JSON for monitoring:**
```bash
./scripts/claude-usage.sh --json | jq '.session.utilization'
```
## Automated Monitoring
### Session Refresh Reminders (Recommended)
Get notified exactly when your 5-hour session quota refreshes!
**Quick Setup:**
```bash
./scripts/session-reminder.sh
```
This creates a **self-scheduling chain** of cron jobs that:
1. Checks your current session expiry time
2. Schedules the next reminder for when your session refreshes
3. Notifies you with current usage stats
4. Auto-removes itself (the new cron takes over)
**What You'll Get:**
```
🔄 Claude Code Session Status
⏱️ Current usage: 44%
⏰ Next refresh: 2h 15m
Your 5-hour quota will reset soon! 🦞
✅ Next reminder scheduled for: Jan 22 at 01:22 AM
```
**How It Works:**
- Each reminder runs `claude-usage.sh` to find the exact session reset time
- Schedules a one-time cron for that exact moment
- Repeats every 5 hours automatically
- Self-correcting if session times ever drift
**Benefits:**
- ✅ Accurate to the minute
- ✅ No manual scheduling needed
- ✅ Adapts to your actual usage patterns
- ✅ Minimal API calls (only when needed)
### Reset Detection Monitor (Alternative)
Get automatic notifications when your Claude Code quotas reset by polling usage.
**Quick Setup:**
```bash
# Test once
./scripts/monitor-usage.sh
# Setup automated monitoring (runs every 30 minutes)
./scripts/setup-monitoring.sh
```
Or add via Clawdbot directly:
```bash
# Check every 30 minutes
clawdbot cron add --cron "*/30 * * * *" \
--message "cd /Users/ali/clawd/skills/claude-code-usage && ./scripts/monitor-usage.sh" \
--name "Claude Code Usage Monitor" \
--session isolated --deliver --channel telegram
```
**What You'll Get:**
```
🎉 Claude Code Session Reset!
⏱️ Your 5-hour quota has reset
📊 Usage: 2%
⏰ Next reset: 4h 58m
Fresh usage available! 🦞
```
**How It Works:**
1. **Monitors usage** every 30 minutes (configurable)
2. **Detects resets** when usage drops significantly (>10% or <5%)
3. **Sends notifications** via Telegram when resets occur
4. **Tracks state** in `/tmp/claude-usage-state.json`
**Customization:**
```bash
# Change check interval
clawdbot cron add --cron "*/15 * * * *" ... # Every 15 minutes
clawdbot cron add --cron "0 * * * *" ... # Every hour
# Custom state file location
STATE_FILE=/path/to/state.json ./scripts/monitor-usage.sh
```
### Which Monitoring Method?
| Feature | Session Reminder | Reset Detection |
|---------|-----------------|-----------------|
| Accuracy | ✅ Exact minute | ~30min window |
| API calls | Minimal | Every check |
| Notification timing | Right on reset | Up to 30min delay |
| Setup | One command | One command |
| Maintenance | Self-scheduling | Cron runs forever |
**Recommendation:** Use **Session Reminder** for precise, real-time notifications.
## Troubleshooting
**No credentials found:**
- Ensure Claude Code CLI is installed and authenticated
- Run `claude` once to trigger OAuth flow
**API request failed:**
- Check internet connection
- Verify OAuth token hasn't expired
- Try `--fresh` to force new request
**Linux users:**
Install `libsecret` for credential storage:
```bash
# Debian/Ubuntu
sudo apt install libsecret-tools
# Fedora/RHEL
sudo dnf install libsecret
```
